WALLACE E. STRATTON, OF NEW YORK, N. Y.

TURNSTILE.

To all whom it may concern:

Be it known that I, WALLACE E. STRAT- TON, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Turnstiles, of which the following is a specification.

This invention relates to improvements in coin controlled turnstiles, whereby the collection of fares on street cars, subway and elevated railroads, and the price of admis sion to places of amusement, where a coin of a single denomination is charged, will be automatically made Without loss.

My object is to provide a-turnstile of this character which will take up the least possible room, in order that it may be positioned in narrow passageways: to so arrange the mechanism that it may be contained in a. narrow case. adapted to be fitted into the end walls of a car or into or against the wall of a building entrance, or the like: and, finally, to provide a combination ofturnstile bars and doors whereby the passage of more than one person at a time will be effectually prevented, and which will not inconvenience a person in passing through any more than would an ordinary swing door, except for the slight pause required to insert a coin to release the mechanism.

I attain my objects by constructing the turnstile in the manner illustrated in the accompanying drawings, in which Figure 1 presents a perspective view of the turnstile mechanism, with the front and top of the case removed, and the'doors shown in broken lines; Fig. 2, a plan view thereof with the top of the case removed; Fig. 3, an end view looking from left to right in Figs. 1 and 2, with the end of the case and box containing the coin mechanism removed; Fig. 4, a perspective View showing the closed case and the doors turned in several positions to illustrate the relative movements of the doors and turnstile bars; and Figs. and 6, details of the bar clevating lever and the main door slot shutter, respectively.

Like numerals designate like parts in the several views.

The mechanism is inclosed within a narrow oblong case 1, the width inside of which need not be over eight inches. At the outward side of the case a door 2 is hung on spring hinges midway between the ends to Specification of Letters Patent.

swing in the direction indicated by the arrow; and a second door 3 is hinged to the case at the end of approach, this second door being lower than the first to pcrmit the turnstile bars to pass over it. Within the case is a turnstile-head 4,-carried upon a revoluble standard Attached to this head are four bars, 6, 7, 8, and 9, by pivotal connections, so that they may swing from horizontal position downward into vertical position, and up again to horizontal position, as they pass through the case. A guide rail supports these turnstile bars when in horizontal position; said rail having downwardly inclined return bends at 11' and 12, to guide the rise and fall of the arms in passing through the case. The rail ends 11 and 12 are supported on the standards 13 and 14, respectively.

Pivotally mounted at 15 on the back of the case is a lever 16, provided with a curved cam slot at 17, in engagement with which is a pin 18, on a three arm oscillating lever 19, which is pivoted at on the back of the case. The arm 21 of this lever is coupled to a spring 22, attached at 23 to the back of the case; and the third arm 24 is provided at its end with a spring actuated arm 25, standing at right angles to the arm 24, and adapted to be turned about the arm against the tension of the spring, when passing to the rear of a turnstile bar, as will presently appear. A stop block 26 is fastened to the back of the case. to limit the motion of arm 24 in its upward throw. Around the standard 5 there are fastened four arms 27, projecting out from one another at angles of 90, and provided at their outward ends with rollers 28, which, as the standard revolves are brought into engagement with the lower end of the lever 16.

The fixed support 29, upon which the revoluble standard 5 is mounted, is provided at 30 with ratchet teeth, in engagement with which is a pawl 31, carried by oneof the arms 27, whereby the backward rotation of the standard is prevented.

The lower ends of the turnstile bars, as they rise from vertical to horizontal position, engage the curved metal track plate 32, fastened to the back of the case, said track being provided at its lower end with an outward curve 33; and being bent over at its upper end at 34, for purposes hereinafter described. I

The door 2 has its lower edge set into a preferably formed in a metal channel piece 41, into which the door is. fitted. The bar 38 is slotted at 42 to slide upon a pin 43 fastened to the bottom of the case.

The coin mechanism is contained in a box 44, provided at its upper end with a coin slot 45, said mechanism being adapted to release a latch 46, which normally stands across the path of the turnstile bars.- Any suitable coin controlled mechanism may be employed for operating this latch.

The outward side of the case is provided with a slot 47, through which the turnstile bars pass out from and back into the case, as they rotate. The door 2 is also provided with a slot at 48, through which the bars pass: -Within a space 56 provided therefor in the door, on the side of approach, as indicated by the broken lines in Figs. 2 and 3, is a vertically movable shutter 49,.which is adapted to drop down after a bar has passed beyond it through the slot 48, to prevent-the door from moving forward until the turnstile bars are released by the coin mechanism. This shutter, at its inward end, is cut on an incline at .50, which incline, when the door 2'swings back to its normal position across the passageway, rides up the then projecting turnstile bar, thereby causing the shutter to rise up and pass over the bar. The shutter is notched at 51 to receive the end of a flat spring lock 52, which projects into the shutter space in the door to engage said notch when the door is in closed positlon. When the door is pushed open, the end of the shutter is turned away from engagement with the lock and is released, so that it may be free to ride over the next turnstile bar, when the door is again closed. The shutter at its inward end is also provided with a pin 53, which engages a ver- 1 tical slot 54 in the door, to prevent endwise motion of the shutter and permit it to tilt as it rides over the bars.

The operation of the'turnstile is as fol lows: After depositing a coin in the slot 45, and thereby releasing the mechanism, the person passing the turnstile pushes the door 2, as he would an ordinary swing door. This sets the mechanism inside the "case in operation; the rotation of the bar 6 with the door 2 rotating the turnstile-head, and with it the other bars, and also the arms 27. This causes one of said arms 27 to turn the cam lever 16, and through it the lever 19, thereby causing the outward end of arm 24 on said lever to travel downward on the curve indicated by the broken lines 55 in the bar, and at the same time the lower Fig. 1. As this arm 24 descends, the spring arm 25 meets the turnstile bar 8, which is then moving in the opposite direction, the spring permits the arm to turn and p ass by the bar 8, the bar being held fromswinging outwardvfrom-the standard so as to interfere with the passage of the arm, by the outward curve 33 on. the track 32. After the arm 25 has passed back of the bar 8, it will spring back into position to engagcel.

of cam lever 16 will be released from engagement with the roller on arm 27, which will have passed completely under said arm, thereby freeing lever 19 which, under the action of spring 22, will be thrown back into its normal position. During this return movement'of the lever the arm 25 will press bar 8 forward and upward, thereby rotating the turnstile bars, and positioning the end of the bar 8 in line with the top of the guide rail 10, the bar being prevented from being thrown above this position by means of the curve 34 at the top of the track 32 and being guided in its upward travel by track 32 on the one side and the portion 11 of the guide'rail 10 on the other side. The bar 6 will then have passed back into the case, and onto the downwardly inclined portion 12 of the rail 10, down which it will slide'of its own weight into the position before occupied by the bar 7, thereby effecting the completion of the quarter turn; bar 7 being carried around to the position of bar 8, and the bar 9 being turned out of the case into the position of bar 6. Bar 8 will thus be brought into engagement with the latch 46 of the coin mechanism, and further operation of the turnstile will be prevented until another coin has been deposited. By

this manner of operation, the'bars are inhorizontal position through 180 of their travel, or throughout their movement through the passageway. During this movement of the turnstile bars the doors 2 and 3 will opcrate conj ointly therewith as followst-VVhen the door 2 arrives in the position indicated at 2 in Fig. 4, the turnstile bar 9 will have passed out through slot 47 into position 9', and the pin 39 on bar 38 will have passed along slot 40 in door 3 to the position 39, where it engages the end of the slot. Further movement of door 2 will then cause an opening of the door 3, and when door 2 is in position 2 door 3 will have been thrown across the passageway into position 3, and the bar 9 will have assumed the position 9 When the door 2 arrives at the position 2 it will be noted that the bar 9, being at right angles to the bar 6, which is being carried forward with the door 2, will project into the passageway sufliciently to block the way against a person following. As, 1n this position 2", the door 2 will not permit the first person to pass out of\the' pas- 'notroom for two sageway, he must further open the door, and as he does so the door 3 is thrown backward against the next person to follow, thereby forcing him back out of the passageway, should he attempt to pass through with the first person. The action of the door 2, in turning from 2 to 2 is to suddenly and quickly throw the door 3 backward across the passageway, and door 3 will be held across the passageway during any further movement of door 2 beyond posi tion 2 if required to permit the passage of the first person completely through the passageway; in other words, during the turning of door 2 from position 2 to 2", where it is completely open. As soon as door 2 .is released itswings back into position across the passageway at right angles to the case, and during its backward swing it throws the door 3 to normal open position. As the door 2 swings back, the shutter 49 at its inward end will be brought into engagement with the bar 9, which is then in position at right angles across the passageway; and the shutter will rise and slide over the bar in the manner illustrated in the. full line position of the door in Fig. 4. As soon as the door is back in its closed position, the shutter will drop down in rear of the bar 9, so that the door cannot be pushed open until the turnstile bars are released by the coin mechanism. As soon as the shutter is dropped into position in rear of the bar, the spring lock 52 will engage notch 51 on the shutter, thereby preventing the shutter from being raised to release the door. The turnstile bars cannot be lifted or depressed while movingjhrough the passageway and there is persons to pass through between bars; Should a person attempt to crawl under a bar behind another person preceding, or to squeeze by the end of the bar, he will be caught and held by the door 3, which must close before the person preceding can open door 2 sufficiently toeven squeeze himself through.

Having thus described the features of construction involved in my invention, and without confining myself to any specific details thereof, what I claim as my invention 7 and desire to secure by Letters Patent is- 1. A turnstile comprising a plurality of bars pivotally mounted upon a revoluble standard, means whereby each of said bars consecutively will be made to travel in a horizontal plane during a portion of its revolution, means whereby the bar will be allowed to drop to vertical position and so remain during a further portion of its revolution, and means operated by the. turning of the standard whereby the bar will be elevated in a substantially vertical plane to horizontal position during the remainder of its revolution.

2.- A-turnstile comprising a case provided with a horizontal slot across one side, a rev oluble standard within the case centrally located with relation to the slot, bars pivotally mounted upon said standard, means whereby the bars in succession will be made to travel in a horizontal plane and through said slot during substantially one-half of a revolution, and means for permitting the depression of the bars and means for elevating the bars in substantially vertical planes within the ease during the remainder of a revolu tion.
